摘要：
An optical fiber magnetic field sensor based on lossy mode resonance (LMR) was designed. Furthermore, a hollow core-offset structure was designed to enhance the performance. Due to the destruction of the circular symmetry structure, the sensor has strong birefringence, resulting in x-polarization and y-polarization with two independent resonance valleys. The refractive index changes from 1.358 to 1.390 and a high sensitivity of 11,483.12 nm/RIU was obtained. In addition, the influence of structural parameters on the sensor was investigated. Magnetic field sensitivities of 893 pm/Gs and 754 pm/Gs were obtained theoretically. The feasibility of LMR is demonstrated for magnetic field measurements and a reference is provided for an optical fiber magnetic field.
